A writer in The Builder has cleverly suggested that bridges might be erected in the crowded thoroughfares of London for the convenience of foot passengers, who lose so much valuable time in crossing. As the stairs would occupy a considerable space, and occasion much fatigue, I beg to propose an amendment: Might not the ascending pedestrians be raised up by the descending? The bridge would then resemble the letter H, and occupy but little room. Three or four at a time, stepping into an iron framework, would be gently elevated, walk across, and perform by their weight the same friendly office for others rising on the opposite side. Surely no obstacles can arise which might not be surmounted by ingenuity. If a temporary bridge were erected in one of the parks the experiment might be tried at little cost, and, at any rate, some amusement would be afforded. C.T.
